FIELD OF THE DISCLOSURE

The disclosure is related to consumer goods and, more particularly, tomethods, systems, products, features, services, and other items directedto media playback or some aspect thereof.

BACKGROUND

Options for accessing and listening to digital audio in an out-loudsetting were severely limited until in 2003, when SONOS, Inc. filed forone of its first patent applications, entitled “Method for SynchronizingAudio Playback between Multiple Networked Devices,” and began offering amedia playback system for sale in 2005. The Sonos Wireless HiFi Systemenables people to experience music from virtually unlimited sources viaone or more networked playback devices. Through a software controlapplication installed on a smartphone, tablet, or computer, one can playwhat he or she wants in any room that has a networked playback device.Additionally, using the controller, for example, different songs can bestreamed to each room with a playback device, rooms can be groupedtogether for synchronous playback, or the same song can be heard in allrooms synchronously.

Given the ever growing interest in digital media, there continues to bea need to develop consumer-accessible technologies to further enhancethe listening experience.

DETAILED DESCRIPTION I. Overview

A music discovery process may involve an introduction to various typesof media. For example, a music discovery process may involve introducingcertain sounds, genres of music, musical artists, albums, and musicaltracks, among other types of media. Further, one or more inputs mayinitiate or lead the music discovery process. For instance, an input mayinvolve a selection of a media service for providing music-relatedmedia. In such a case, a music discovery process may follow aservice-based approach that includes an initial selection of a service(e.g., Pandora® Radio, Spotify®, Slacker® Radio, Google Play™, Rhapsody®Music Service, iTunes Radio℠, and others), and then a selection of mediathat is maintained by the selected service.

In some examples, a music discovery process may be guided by variousfeatures of the selected service. For example, consider a musicdiscovery process involving an internet radio service, possibly amongother services. The internet radio service may include a browsing inputfor discovering various types of media. As such, a particular genre ofmusic (e.g., rock, jazz, electronic, and classical) may be entered intothe browsing input and the internet radio service may determine a numberof artists and/or songs related to the particular genre of music.

Further, a music discovery process may be guided by the selectedservice's ability or inability to provide media. For example,considering the scenario above, the internet radio service may providecertain artists, albums, and/or tracks for the particular genre ofmusic. In addition, the internet radio may require additional inputs toidentify particular artists, albums, and/or tracks. In some instances,the internet radio service may provide suggestions to guide or possiblyinfluence the exploration of particular areas of music.

According to examples described herein, a music discovery process mayinvolve inputs that are not initially associated with a particular mediaservice. For example, music discovery tools may be used before aparticular media service is identified to facilitate the identificationof media or exposure to media without first identifying a particularmedia service. As such, a music discovery process may introduce mediawithout initially requiring inputs for selecting a particular mediaservice at the beginning of the process. In such a situation, such musicdiscovery processes may allow exploration of media to minimize orpossibly eliminate potential influences from services. Further, suchmusic discovery processes may allow exploration of a more expansivecollection of media that is not associated with any single, particularmedia service.

As such, examples provided herein relate to a music discovery process.In one aspect, a method is provided. The method involves (a) receivingby a computing device an indication of a search tool from among aplurality of search tools, wherein each search tool of the plurality ofsearch tools is associated with at least one respective media service,(b) receiving by the computing device an indication of a mediacharacteristic, wherein the computing device receives the mediacharacteristic via the indicated search tool, (c) selecting by thecomputing device one or more of the at least one respective mediaservice that maintains media associated with the indicated mediacharacteristic; and (d) sending by the computing device an indication ofthe selected one or more of the at least one respective media service.

In another aspect, a non-transitory computer-readable medium isprovided. The non-transitory computer-readable medium havinginstructions stored thereon that are executable by a computing device tocause the first computing device to perform functions, the functionsinclude (a) receiving by the computing device a selection of a searchtool from among a plurality of search tools, wherein the selected searchtool includes a search input, (b) receiving by the computing device anindication of a media characteristic, wherein the computing devicereceives the media characteristic via the search input, (c) selecting bythe computing device one or more media services that maintain mediaassociated with the indicated media characteristic, and (d) causing thecomputing device to display the one or more media services.

In another example aspect, a method is provided. The method involves (a)receiving by a computing device an indication of a media characteristic,(b) selecting by the computing device one or more media services thatmaintain media associated with the indicated media characteristic, (c)selecting by the computing device a plurality of categories, whereineach category of the plurality of categories is associated with at leastone respective media service of the one or more media services, (d)sending by the computing device an indication of the plurality ofcategories, (e) receiving by the computing device an indication of aparticular category among the plurality of categories, and (f) afterreceiving the indication of the particular category, sending by thecomputing device an indication of the at least one respective mediaservice of the one or more media services associated with the particularcategory.

In yet another example aspect, another method is provided. The methodinvolves, (a) receiving by the computing device a selection of a searchtool from among a plurality of search tools, wherein the selected searchtool includes a search input, (b) receiving by the computing device anindication of a media characteristic, wherein the computing devicereceives the media characteristic via the search input, (c) selecting bythe computing device one or more of the media services that maintainmedia associated with the indicated media characteristic, and (d)causing the computing device to display the one or more media services.

In one other example aspect, an additional method is provided. Themethod involves (a) displaying by a computing device a search input, (b)receiving by the computing device an indication of a mediacharacteristic, wherein the computing device receives the mediacharacteristic via the search input, (c) selecting by the computingdevice one or more media services that maintain media associated withthe indicated media characteristic, (d) selecting by the computingdevice a plurality of categories, wherein each category of the pluralityof categories is associated with at least one respective media serviceof the one or more media services, (e) displaying by the computingdevice the plurality of categories, (f) receiving by the computingdevice an indication of a particular category among the plurality ofcategories, and (g) after receiving the indication of the particularcategory, displaying by the computing device the at least one respectivemedia service associated with the particular category.

It will be understood by one of ordinary skill in the art that thisdisclosure includes numerous other examples. While some examplesdescribed herein may refer to functions performed by given actors suchas “users” and/or other entities, it should be understood that this isfor purposes of explanation only. The claims should not be interpretedto require action by any such example actor unless explicitly requiredby the language of the claims themselves.

II. Example Network Configuration

FIG. 1 shows an example network configuration 100 in which one or moreexamples disclosed herein may be practiced or implemented. As shown, thenetwork configuration 100 may include a computing device 102, which maybe referred to herein as media server device 102. Further, the networkconfiguration 100 may also include two or more media playback systems106 and 108. Yet further, the network configuration 100 may also includetwo or more computing devices 110 and 112, which may be referred to asserver devices 110 and 112, respectively. In addition, the networkconfiguration 100 may also include a cloud network 114. In someexamples, the media server device 102 may include a database 104. Inother examples, the database 104 may be located on a differentnetwork-connected element, perhaps one that is not shown. Accordingly,it should be understood that the network configuration 100 may includeadditional network-connected elements as well.

The cloud network 114 may communicatively couple the various networkelements of the network configuration 100. In such an arrangement, themedia server device 102 may communicate with the media playback systems106-108 and/or the server devices 110-112 via the cloud network 114.Similarly, the media playback systems 106-108 may communicate with theserver devices 110-112 via the cloud network 114. Further, the mediaplayback systems 106-108 may communicate with one another via the cloudnetwork 114. The cloud network 114 may be, for example, a wide-areanetwork (WAN). As such, the cloud network 114 may include the Internetand/or one or more cellular networks, among other networks.

Generally, media playback systems 106-108 may be any type of mediaplayback system configured to receive and transmit data over a datanetwork and playback media items. Each of the media playback systems106-108 may be physically located in different locations. Alternatively,the media playback systems 106-108 may be physically located in the samelocation (e.g., an office building). In practice, a media playbacksystem 106-108 may include one or more playback devices. An example ofsuch a media playback system is discussed in further detail below withreference to example media playback system 200.

One or more of server devices 110-112 may include at least oneprocessor, data storage, and a network interface, among othercomponents. One or more of server devices 110-112 may be configured tostore media items (e.g., a media library) and/or access such media itemsto transmit to a playback device. One or more of server devices 110-112may also create or obtain metadata related to the media items, as wellas store such metadata.

In practice, the server devices 110-112 may provide media or mediacontent to the media playback systems 106-108. In particular, each mediaservice may provide streaming media and/or media downloads, among otherexamples. Each server device may provide “Internet radio” service and/or“on-demand” service (e.g., where a user may request a particular mediaitem) to one or both of the media playback systems 106-108. When aserver devices 110-112 provides a media item to a media playback system,the server device may provide metadata along with the media item.

The media server device 102 may include a network interface, aprocessing unit, and data storage, all of which may be communicativelylinked together by a system bus, network, or other connection mechanism.The network interface may facilitate data flow between the media serverdevice 102 and other network elements on the cloud network 114. Theprocessing unit may include one or more general purpose processorsand/or one or more special purpose processors and may be integrated inwhole or in part with the network interface. The data storage mayinclude a non-transitory computer-readable medium, such as optical,magnetic, or flash memory, and may be integrated in whole or in partwith the processing unit. The data storage may then include programinstructions that are executable by the processing unit to carry outvarious functions described herein.

In example implementations, the data storage may also include thedatabase 104 that may contain data related to media items. The data maybe stored in the form of a table or the like. In some implementations,the database 104 may include data that may be used by the media serverdevice 102 to perform cross-service linking functions. Accordingly, thedatabase 104 may be referred to herein as a “cross-service linkingdatabase.” In other examples, the media server device 102 may utilize anexternal database or the like to perform cross-service linkingfunctions.

In general, cross-service linking involves the media system server 102receiving a first media-item identifier of a first service provider andoutputting a second media-item identifier of a second service provider,where the first media-item identifier and the second media-itemidentifier identify substantially the same underlying media content. Inpractice, each media service server 110-112 may maintain a respectivedatabase that includes media provided by the respective media service.And typically, each respective database may be maintained in a uniquemanner. As such, without using the cross-service linking database 104,information used to retrieve media from the media service server 110 maynot be useful for retrieving media from the media service server 112.Accordingly, the cross-service linking database 104 may facilitateaccessing media from a given media service (e.g., the media serviceserver 112) using information related to a different media service(e.g., the media service server 110).

In example implementations, the media system server 102 may beconfigured to maintain the cross-service linking database 104, which mayinvolve a number of functions. For example, the media system server 102may receive a first message from the media playback system 106. Forinstance, after or while the media playback system 106 plays a firstmedia item, the media playback system 106 may transmit the first messageto the media system server 102. The first message may identify a firstservice (e.g., service provided by the media service server 110) used bythe media playback system 106 to obtain the first media item forplayback. The first message may also include a first service media-itemidentifier that the media service server 110 uses to identify the firstmedia item. Further, the first message may include a first metadata thatis associated with the first media item (e.g., a track title, artistname, album title, etc.). The media system server 102 may store some orall of this first message information in the cross-service linkingdatabase 104.

The media system server 102 may thereafter receive a second message fromthe media playback system 108. As with the first message, the secondmessage may identify a second service (e.g., service provided by themedia service server 112) used by the media playback system 108 toobtain a second media item for playback, a second service media-itemidentifier used to identify the second media item, and a second metadatathat is associated with the second media item. The media system server102 may store some or all of this second message information in thedatabase 104.

The media system server 102 may then compare the second metadata withthe first metadata that was previously stored in the database 104 todetermine if, and to what extent, the first metadata and the secondmetadata have any similarities. If the media system server 102determines that the second metadata and the first metadata aresubstantially similar, the media system server 102 may infer that thefirst media item and the second media item have comparable underlyingmedia content. In response, the media system server 102 may storeassociation data in the database 104 indicating that the first servicemedia-item identifier and the second service media-item identifieridentify media items that include the same content. Association data maybe generated for storage in database 104 in other ways as well.

As a result of such an association, the media system server 102 may usethe cross-service linking database 104 to retrieve the second servicemedia-item identifier using the first service media-item identifier andvice versa. In practice, the media system server 102 may performcross-service linking for a plurality of media items. In this way, auser who does not have access to a first service but does have access toa second service may still obtain desired media content from the secondservice using media-item information of the first service.

For example, the media server device 102 may receive a message from themedia playback system 106. For instance, after or while the mediaplayback system 106 plays a media item, the media playback system 106may transmit the message to the media server device 102. The message mayidentify a service (e.g., a service provided by the server device 110)used by the media playback system 106 to obtain the media item forplayback. The message may also include an identifier that the serverdevice 110 uses to identify the media item. Further, the message mayinclude metadata that is associated with the media (e.g., a track title,artist name, album title, etc.). The media server device 102 may storesome or all of this message information in the database 104.

In some implementations, some or all of the cross-service linkingfunctions described above may be carried out by any other suitablenetwork element. Furthermore, in example implementations, one networkelement (e.g., the media server device 102) may perform cross-servicelinking functions to build one or more cross-service linking databases,and then another network element (e.g., a computing device of either ofthe media playback systems 106, 108) may locally store and/or referencethe cross-service linking database.

III. Example Media Playback System

FIG. 2 shows an example configuration of a media playback system 200.The media playback system 200 as shown is associated with an examplehome environment having several rooms and spaces, such as for example, amaster bedroom, an office, a dining room, and a living room. As shown inthe example of FIG. 2, the media playback system 200 includes playbackdevices 202-224, computing devices 226 and 228 (also referred to hereinas control devices 226 and 228, respectively), and a wired or wirelessnetwork router 230.

Further discussions relating to the different components of the examplemedia playback system 200 and how the different components may interactto provide a music discovery may be found in the following sections.While discussions herein may generally refer to the example mediaplayback system 200, technologies described herein are not limited toapplications within, among other things, the home environment as shownin FIG. 2. For instance, the technologies described herein may be usefulin environments where multi-zone audio may be desired, such as, forexample, a commercial setting like a restaurant, mall or airport, avehicle like a sports utility vehicle (SUV), bus or car, a ship or boat,an airplane, and so on.

a. Example Playback Devices

FIG. 3 shows a functional block diagram of an example playback device300 that may be configured to be one or more of the playback devices202-224 of the media playback system 200 of FIG. 2. The playback device300 may include a processor 302, software components 304, memory 306,audio processing components 308, audio amplifier(s) 310, speaker(s) 312,and a network interface 314 including wireless interface(s) 316 andwired interface(s) 318. In one case, the playback device 300 may notinclude the speaker(s) 312, but rather a speaker interface forconnecting the playback device 300 to external speakers. In anothercase, the playback device 300 may include neither the speaker(s) 312 northe audio amplifier(s) 310, but rather an audio interface for connectingthe playback device 300 to an external audio amplifier or audio-visualreceiver.

In one example, the processor 302 may be a clock-driven computingcomponent configured to process input data according to instructionsstored in the memory 306. The memory 306 may be a tangiblecomputer-readable medium configured to store instructions executable bythe processor 302. For instance, the memory 306 may be data storage thatcan be loaded with one or more of the software components 304 executableby the processor 302 to achieve certain functions. In one example, thefunctions may involve the playback device 300 retrieving audio data froman audio source or another playback device. In another example, thefunctions may involve the playback device 300 sending audio data toanother device or playback device on a network. In yet another example,the functions may involve pairing of the playback device 300 with one ormore playback devices to create a multi-channel audio environment.

Certain functions may involve the playback device 300 synchronizingplayback of audio content with one or more other playback devices.During synchronous playback, a listener will preferably not be able toperceive time-delay differences between playback of the audio content bythe playback device 300 and the one or more other playback devices. U.S.Pat. No. 8,234,395 entitled, “System and method for synchronizingoperations among a plurality of independently clocked digital dataprocessing devices,” which is hereby incorporated by reference, providesin more detail some examples for audio playback synchronization amongplayback devices.

The memory 306 may further be configured to store data associated withthe playback device 300, such as one or more zones and/or zone groupsthe playback device 300 is a part of, audio sources accessible by theplayback device 300, or a playback queue that the playback device 300(or some other playback device) may be associated with. The data may bestored as one or more state variables that are periodically updated andused to describe the state of the playback device 300. The memory 306may also include the data associated with the state of the other devicesof the media system, and shared from time to time among the devices sothat one or more of the devices have the most recent data associatedwith the system. Other examples are also possible.

The audio processing components 308 may include one or moredigital-to-analog converters (DAC), an audio preprocessing component, anaudio enhancement component or a digital signal processor (DSP), and soon. In one embodiment, one or more of the audio processing components308 may be a subcomponent of the processor 302. In one example, audiocontent may be processed and/or intentionally altered by the audioprocessing components 308 to produce audio signals. The produced audiosignals may then be provided to the audio amplifier(s) 310 foramplification and playback through speaker(s) 312. Particularly, theaudio amplifier(s) 310 may include devices configured to amplify audiosignals to a level for driving one or more of the speakers 312. Thespeaker(s) 312 may include an individual transducer (e.g., a “driver”)or a complete speaker system involving an enclosure with one or moredrivers. A particular driver of the speaker(s) 312 may include, forexample, a subwoofer (e.g., for low frequencies), a mid-range driver(e.g., for middle frequencies), and/or a tweeter (e.g., for highfrequencies). In some cases, each transducer in the one or more speakers312 may be driven by an individual corresponding audio amplifier of theaudio amplifier(s) 310. In addition to producing analog signals forplayback by the playback device 300, the audio processing components 308may be configured to process audio content to be sent to one or moreother playback devices for playback.

Audio content to be processed and/or played back by the playback device300 may be received from an external source, such as via an audioline-in input connection (e.g., an auto- detecting 3.5 mm audio line-inconnection) or the network interface 314.

The network interface 314 may be configured to facilitate a data flowbetween the playback device 300 and one or more other devices on a datanetwork. As such, the playback device 300 may be configured to receiveaudio content over the data network from one or more other playbackdevices in communication with the playback device 300, network deviceswithin a local area network, or audio content sources over a wide areanetwork such as the Internet. In one example, the audio content andother signals transmitted and received by the playback device 300 may betransmitted in the form of digital packet data containing an InternetProtocol (IP)-based source address and IP-based destination addresses.In such a case, the network interface 314 may be configured to parse thedigital packet data such that the data destined for the playback device300 is properly received and processed by the playback device 300.

As shown, the network interface 314 may include wireless interface(s)316 and wired interface(s) 318. The wireless interface(s) 316 mayprovide network interface functions for the playback device 300 towirelessly communicate with other devices (e.g., other playbackdevice(s), speaker(s), receiver(s), network device(s), control device(s)within a data network the playback device 300 is associated with) inaccordance with a communication protocol (e.g., any wireless standardincluding IEEE 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.15, 4Gmobile communication standard, and so on). The wired interface(s) 318may provide network interface functions for the playback device 300 tocommunicate over a wired connection with other devices in accordancewith a communication protocol (e.g., IEEE 802.3). While the networkinterface 314 shown in FIG. 3 includes both wireless interface(s) 316and wired interface(s) 318, the network interface 314 may in someexamples include only wireless interface(s) or only wired interface(s).

In one example, the playback device 300 and one other playback devicemay be paired to play two separate audio components of audio content.For instance, playback device 300 may be configured to play a leftchannel audio component, while the other playback device may beconfigured to play a right channel audio component, thereby producing orenhancing a stereo effect of the audio content. The paired playbackdevices (also referred to as “bonded playback devices”) may further playaudio content in synchrony with other playback devices.

In another example, the playback device 300 may be sonicallyconsolidated with one or more other playback devices to form a single,consolidated playback device. A consolidated playback device may beconfigured to process and reproduce sound differently than anunconsolidated playback device or playback devices that are paired,because a consolidated playback device may have additional speakerdrivers through which audio content may be rendered. For instance, ifthe playback device 300 is a playback device designed to render lowfrequency range audio content (i.e. a subwoofer), the playback device300 may be consolidated with a playback device designed to render fullfrequency range audio content. In such a case, the full frequency rangeplayback device, when consolidated with the low frequency playbackdevice 300, may be configured to render only the mid and high frequencycomponents of audio content, while the low frequency range playbackdevice 300 renders the low frequency component of the audio content. Theconsolidated playback device may further be paired with a singleplayback device or yet another consolidated playback device.

By way of illustration, SONOS, Inc. presently offers (or has offered)for sale certain playback devices including a “PLAY:1,” “PLAY:3,”“PLAY:5,” “PLAYBAR,” “CONNECT:AMP,” “CONNECT,” and “SUB.” Any otherpast, present, and/or future playback devices may additionally oralternatively be used to implement the playback devices of examplesdisclosed herein. Additionally, it is understood that a playback deviceis not limited to the example illustrated in FIG. 3 or to the SONOSproduct offerings. For example, a playback device may include a wired orwireless headphone. In another example, a playback device may include orinteract with a docking station for personal mobile media playbackdevices. In yet another example, a playback device may be integral toanother device or component such as a television, a lighting fixture, orsome other device for indoor or outdoor use.

b. Example Playback Zone Configurations

Referring back to the media playback system 200 of FIG. 2, theenvironment may have one or more playback zones, each with one or moreplayback devices. The media playback system 200 may be established withone or more playback zones, after which one or more zones may be added,or removed to arrive at the example configuration shown in FIG. 2. Eachzone may be given a name according to a different room or space such asan office, bathroom, master bedroom, bedroom, kitchen, dining room,living room, and/or balcony. In one case, a single playback zone mayinclude multiple rooms or spaces. In another case, a single room orspace may include multiple playback zones.

As shown in FIG. 2, the balcony, dining room, kitchen, bathroom, office,and bedroom zones each have one playback device, while the living roomand master bedroom zones each have multiple playback devices. In theliving room zone, playback devices 204, 206, 208, and 210 may beconfigured to play audio content in synchrony as individual playbackdevices, as one or more bonded playback devices, as one or moreconsolidated playback devices, or any combination thereof. Similarly, inthe case of the master bedroom, playback devices 222 and 224 may beconfigured to play audio content in synchrony as individual playbackdevices, as a bonded playback device, or as a consolidated playbackdevice.

In one example, one or more playback zones in the environment of FIG. 2may each be playing different audio content. For instance, the user maybe grilling in the balcony zone and listening to hip hop music beingplayed by the playback device 202 while another user may be preparingfood in the kitchen zone and listening to classical music being playedby the playback device 214. In another example, a playback zone may playthe same audio content in synchrony with another playback zone. Forinstance, the user may be in the office zone where the playback device218 is playing the same rock music that is being playing by playbackdevice 202 in the balcony zone. In such a case, playback devices 202 and218 may be playing the rock music in synchrony such that the user mayseamlessly (or at least substantially seamlessly) enjoy the audiocontent that is being played out-loud while moving between differentplayback zones. Synchronization among playback zones may be achieved ina manner similar to that of synchronization among playback devices, asdescribed in previously referenced U.S. Pat. No. 8,234,395.

As suggested above, the zone configurations of the media playback system200 may be dynamically modified, and in some examples, the mediaplayback system 100 supports numerous configurations. For instance, if auser physically moves one or more playback devices to or from a zone,the media playback system 200 may be reconfigured to accommodate thechange(s). For instance, if the user physically moves the playbackdevice 202 from the balcony zone to the office zone, the office zone maynow include both the playback device 218 and the playback device 202.The playback device 202 may be paired or grouped with the office zoneand/or renamed if so desired via a control device such as the controldevices 226 and 228. On the other hand, if the one or more playbackdevices are moved to a particular area in the home environment that isnot already a playback zone, a new playback zone may be created for theparticular area.

Further, different playback zones of the media playback system 200 maybe dynamically combined into zone groups or split up into individualplayback zones. For instance, the dining room zone and the kitchen zone214 may be combined into a zone group for a dinner party such thatplayback devices 212 and 214 may render audio content in synchrony. Onthe other hand, the living room zone may be split into a television zoneincluding playback device 204, and a listening zone including playbackdevices 206, 208, and 210, if the user wishes to listen to music in theliving room space while another user wishes to watch television.

c. Example Control Devices

FIG. 4 shows a functional block diagram of an example computing device400 which may also be referred to as control device 400. In someinstances, computing device 400 may be configured to be one or both ofthe control devices 226 and 228 of the media playback system 200. Asshown, the computing device 400 may include a processor 402, memory 404,a network interface 406, and a user interface 408. In one example, thecomputing device 400 may be a dedicated controller for the mediaplayback system 200. In another example, the computing device 400 may bea network device on which media playback system controller applicationsoftware may be installed, such as for example, an iPhone™, iPad™ or anyother smart phone, tablet or network device (e.g., a networked computersuch as a PC or Mac™)

The processor 402 may be configured to perform functions relevant tofacilitating user access, control, and configuration of the mediaplayback system 200. The memory 404 may be configured to storeinstructions executable by the processor 402 to perform those functions.The memory 404 may also be configured to store the media playback systemcontroller application software and other data associated with the mediaplayback system 200 and the user.

In one example, the network interface 406 may be based on an industrystandard (e.g., infrared, radio, wired standards including IEEE 802.3,wireless standards including IEEE 802.11a, 802.11b, 802.11g, 802.11n,802.11ac, 802.15, 4G mobile communication standard, and so on). Thenetwork interface 406 may provide a means for the control device 400 tocommunicate with other devices in the media playback system 200. In oneexample, data and information (e.g., such as a state variable) may becommunicated between control device 400 and other devices via thenetwork interface 406. For instance, playback zone and zone groupconfigurations in the media playback system 200 may be received by thecontrol device 400 from a playback device or another network device, ortransmitted by the control device 400 to another playback device ornetwork device via the network interface 406. In some cases, the othernetwork device may be another control device.

Playback device control commands such as volume control and audioplayback control may also be communicated from the control device 400 toa playback device via the network interface 406. As suggested above,changes to configurations of the media playback system 200 may also beperformed by a user using the control device 400. The configurationchanges may include adding/removing one or more playback devices to/froma zone, adding/removing one or more zones to/from a zone group, forminga bonded or consolidated player, separating one or more playback devicesfrom a bonded or consolidated player, among others. Accordingly, thecontrol device 400 may sometimes be referred to as a controller, whetherthe control device 400 is a dedicated controller or a network device onwhich media playback system controller application software isinstalled.

The user interface 408 of the control device 400 may be configured tofacilitate user access and control of the media playback system 200, byproviding a controller interface such as the controller interface 500shown in FIG. 5. The controller interface 500 includes a playbackcontrol region 510, a playback zone region 520, a playback status region530, a playback queue region 540, and an audio content sources region550. The user interface 500 as shown is just one example of a userinterface that may be provided on a network device such as the controldevice 400 of FIG. 4 (and/or the control devices 226 and 228 of FIG. 2)and accessed by users to control a media playback system such as themedia playback system 200. Other user interfaces of varying formats,styles, and interactive sequences may alternatively be implemented onone or more network devices to provide comparable control access to amedia playback system.

The playback control region 510 may include selectable (e.g., by way oftouch or by using a cursor) icons to cause playback devices in aselected playback zone or zone group to play or pause, fast forward,rewind, skip to next, skip to previous, enter/exit shuffle mode,enter/exit repeat mode, enter/exit cross fade mode. The playback controlregion 510 may also include selectable icons to modify equalizationsettings, and playback volume, among other possibilities.

The playback zone region 520 may include representations of playbackzones within the media playback system 200. In some examples, thegraphical representations of playback zones may be selectable to bringup additional selectable icons to manage or configure the playback zonesin the media playback system, such as a creation of bonded zones,creation of zone groups, separation of zone groups, and renaming of zonegroups, among other possibilities.

For example, as shown, a “group” icon may be provided within each of thegraphical representations of playback zones. The “group” icon providedwithin a graphical representation of a particular zone may be selectableto bring up options to select one or more other zones in the mediaplayback system to be grouped with the particular zone. Once grouped,playback devices in the zones that have been grouped with the particularzone will be configured to play audio content in synchrony with theplayback device(s) in the particular zone. Analogously, a “group” iconmay be provided within a graphical representation of a zone group. Inthis case, the “group” icon may be selectable to bring up options todeselect one or more zones in the zone group to be removed from the zonegroup. Other interactions and implementations for grouping andungrouping zones via a user interface such as the user interface 500 arealso possible. The representations of playback zones in the playbackzone region 520 may be dynamically updated as playback zone or zonegroup configurations are modified.

The playback status region 530 may include graphical representations ofaudio content that is presently being played, previously played, orscheduled to play next in the selected playback zone or zone group. Theselected playback zone or zone group may be visually distinguished onthe user interface, such as within the playback zone region 520 and/orthe playback status region 530. The graphical representations mayinclude track title, artist name, album name, album year, track length,and other relevant information that may be useful for the user to knowwhen controlling the media playback system via the user interface 500.

The playback queue region 540 may include graphical representations ofaudio content in a playback queue associated with the selected playbackzone or zone group. In some examples, each playback zone or zone groupmay be associated with a playback queue containing informationcorresponding to zero or more audio items for playback by the playbackzone or zone group. For instance, each audio item in the playback queuemay comprise a uniform resource identifier (URI), a uniform resourcelocator (URL) or some other identifier that may be used by a playbackdevice in the playback zone or zone group to find and/or retrieve theaudio item from a local audio content source or a networked audiocontent source, possibly for playback by the playback device.

In one example, a playlist may be added to a playback queue, in whichcase information corresponding to each audio item in the playlist may beadded to the playback queue. In another example, audio items in aplayback queue may be saved as a playlist. In a further example, aplayback queue may be empty, or populated but “not in use” when theplayback zone or zone group is playing continuously streaming audiocontent, such as Internet radio that may continue to play untilotherwise stopped, rather than discrete audio items that have playbackdurations. In an alternative embodiment, a playback queue can includeInternet radio and/or other streaming audio content items and be “inuse” when the playback zone or zone group is playing those items. Otherexamples are also possible.

The graphical representations of audio content in the playback queueregion 540 may include track titles, artist names, track lengths, andother relevant information associated with the audio content in theplayback queue. In one example, graphical representations of audiocontent may be selectable to bring up additional selectable icons tomanage and/or manipulate the playback queue and/or audio contentrepresented in the playback queue. For instance, a represented audiocontent may be removed from the playback queue, moved to a differentposition within the playback queue, or selected to be playedimmediately, or after any currently playing audio content, among otherpossibilities. A playback queue associated with a playback zone or zonegroup may be stored in a memory on one or more playback devices in theplayback zone or zone group, on a playback device that is not in theplayback zone or zone group, and/or some other designated device.

The audio content sources region 550 may include graphicalrepresentations of selectable audio content sources from which audiocontent may be retrieved and played by the selected playback zone orzone group. Discussions pertaining to audio content sources may be foundin the following section.

d. Example Audio Content Sources

As indicated previously, one or more playback devices in a zone or zonegroup may be configured to retrieve media for playback audio content(e.g. according to a corresponding URI or URL for the audio content)from a variety of available audio content sources. In one example, audiocontent may be retrieved by a playback device directly from acorresponding audio content source (e.g., a line-in connection). Inanother example, audio content may be provided to a playback device overa network via one or more other playback devices or network devices.

Example audio content sources may include a memory of one or moreplayback devices in a media playback system such as the media playbacksystem 200 of FIG. 2, local music libraries on one or more networkdevices (such as a control device, a network-enabled personal computer,or a networked-attached storage (NAS), for example), streaming audioservices providing audio content via the Internet (e.g., the mediaservice servers 135-145), or audio sources connected to the mediaplayback system via a line-in input connection on a playback device ornetwork devise, among other possibilities.

In some examples, audio content sources may be regularly added orremoved from a media playback system such as the media playback system200 of FIG. 2. In one example, an indexing of audio items may beperformed whenever one or more audio content sources are added, removedor updated. Indexing of audio items may involve scanning foridentifiable audio items in all folders/directory shared over a networkaccessible by playback devices in the media playback system, andgenerating or updating an audio content database containing metadata(e.g., title, artist, album, track length, among others) and otherassociated information, such as a URI or URL for each identifiable audioitem found. Other examples for managing and maintaining audio contentsources may also be possible.

The above discussions relating to playback devices, controller devices,playback zone configurations, and media content sources provide onlysome examples of operating environments within which functions andmethods described below may be implemented. Other operating environmentsand configurations of media playback systems, playback devices, andnetwork devices not explicitly described herein may also be applicableand suitable for implementation of the functions and methods. cl IV.Example Methods of Music Discovery

As discussed above, music discovery processes may include processes foridentifying various types of media. In some instances, such processesmay identify media without initially having to select a particular mediaservice for providing the media or prior to having to select the mediaservice. In addition, various music discovery tools may be used tofacilitate the process in identifying various types of media content.

For method 600 of FIG. 6, method 1000 of FIG. 10, and method 1100 ofFIG. 11 and other processes and methods disclosed herein, the flowchartsshow functionality and operation of one possible implementation ofpresent examples. In this regard, each block may represent a module, asegment, or a portion of program code, which includes one or moreinstructions executable by a processor for implementing specific logicalfunctions or steps in the process. The program code may be stored on anytype of computer-readable medium, for example, such as a storage deviceincluding a disk or hard drive. The computer-readable medium may includenon-transitory computer-readable medium, for example, such ascomputer-readable media that stores data for short periods of time likeregister memory, processor cache and Random Access Memory (RAM). Thecomputer-readable medium may also include non-transitory media, such assecondary or persistent long term storage, like read only memory (ROM),optical or magnetic disks, compact-disc read only memory (CD-ROM), forexample. The computer-readable media may also be any other volatile ornon-volatile storage systems. The computer-readable medium may beconsidered a computer-readable storage medium, for example, or atangible storage device. In addition, for the methods and processesdisclosed herein, each block in FIGS. 6, 10, and 11 may representcircuitry that is wired to perform the specific logical functions in theprocess.

Furthermore, although the blocks are illustrated in sequential order,these blocks may also be performed in parallel, and/or in a differentorder than those described herein. Also, the various blocks may becombined into fewer blocks, divided into additional blocks, and/orremoved based upon the desired implementation.

For clarity, the methods 600, 1000, and 1100 may be described hereinwith reference to FIGS. 7, 8, and 9. It should be understood, however,that this is for purposes of example and explanation only and that theoperations of the methods should not be limited by these figures.

1. First Example Method of Music Discovery

The method 600 shown in FIG. 6 presents an embodiment of a method thatmay be implemented within the network configuration 100. In particular,method 600 may be implemented by any of the computing devices 102, 110,and 112, as discussed above in relation to FIG. 1. It should beunderstood that method 600 may be carried out in other suitable networkconfigurations and/or by other suitable network elements as well. Method600 may include one or more operations, functions, or actions asillustrated by one or more of blocks 602-608.

The method 600 begins at block 602 with receiving by a computing devicean indication of a search tool from among a plurality of search tools,where each search tool of the plurality of search tools is associatedwith at least one respective media service. At block 604, the method 600involves receiving by the computing device an indication of a mediacharacteristic, where the computing device receives the mediacharacteristic via the indicated search tool. At block 606, the method600 involves selecting by the computing device one or more of the atleast one respective media service that maintains media associated withthe indicated media characteristic. At block 608, the method 600involves sending by the computing device an indication of the selectedone or more of the at least one respective media service. The blocksshown in FIG. 6 are discussed in further detail below.

a. Receiving Indication of Search Tool from Among Plurality of SearchTools

The method 600 begins at block 602 with receiving by a computing devicean indication of a search tool from among a plurality of search tools,where each search tool of the plurality of search tools is associatedwith at least one respective media service. As noted, the computingdevice may be any one of computing devices 102, 110, and 112. Forexample, one or more of computing devices 102, 110, and 112 may receivean indication of a search tool. Further, a computing device in the mediaplayback systems 106 and/or 108 may receive an indication of a searchtool and send the indication to one or more of the computing device 102,110, and 112. As such, the computing devices 102, 110, and 112 mayreceive the indication of the search tool over the cloud network 114.

FIGS. 7 and 8 show representations of example search tools. As shown inFIGS. 7 and 8, the representations 710 and 810, respectively, may bepart of a music discovery process. For example, representations 710 and810 may be music discovery tools displayed on a computing device inmedia playback systems 106 and/or 108 to facilitate the music discoveryprocess. In particular, the representations 710 and 810 may provide aplurality of search tools without initially requiring an indicationregarding a particular media service.

A search tool may be any tool, device, program, and/or interface fordiscovering media content. For example, a search tool may include asearch input for receiving information used to discover media content.In some instances, the search tool may receive information that includesmedia characteristics to guide the music discovery process. Theinformation received may be related to an emotion, a feeling, a place,and/or a theme of the discovery process, among other possibilities. Assuch, different types of information or media characteristics may bereceived throughout the music discovery process. For example, therepresentations 710 and 810 include a search tool, a browse tool, “TheSentence” tool, a “time of day” tool (illustrating “It's a Thursdayafternoon . . . ”), and a feeling tool (illustrating “How are youfeeling?”), among other possible types of tools. As illustrated by theellipses, there may be other search tools in the representations 710 and810 to support the music discovery process.

Further, a user may or may not be registered with any particular mediaservice for using the search tools. As such, the user may utilize thesearch tools as part of the music discovery process without initiallyselecting a particular media service. Further, in some instances, theuser may be automatically registered to the services and/or prompted toregister to the services. For example, the user may be prompted with aquestion, e.g., “Would you like to sign up to this service with youremail, ‘user@email.com’, and password, ‘password123’?”

As noted, one or more of computing devices 102, 110, and 112 may receivean indication of a search tool. For example, consider a scenario suchthat representation 710 is displayed on a computing device in mediaplayback systems 106 and/or 108. As shown in FIG. 7, the computingdevice may receive an indication shown as the “It's a Thursday afternoon. . . ” search tool, possibly through a touchpad interface on thecomputing device. Further, the computing device may send the indicationto one or more of computing devices 102, 110, and 112. As such, one ormore of computing devices 102, 110, and 112 may receive the indicationover cloud network 114.

In another example, consider that representation 810 is displayed on acomputing device in media playback systems 106 and/or 108. As shown inFIG. 8, the control device may receive an indication of “The Sentence”search tool, possibly through a touchpad interface on the computingdevice. Further, the computing device may send the indication to one ormore of computing devices 102, 110, and 112. As such, one or more ofthese computing devices 102, 110, and 112 may receive the indicationover cloud network 114.

In yet another example, consider that a computing device in mediaplayback systems 106 and/or 108 receives an indication of the “search”and/or “browse” tool in the representations 710 and 810. Further, thecomputing device may send the indication to one or more computingdevices 102, 110, and 112. As such, one or more of these computingdevices 102, 110, and 112 may receive the indication over cloud network114.

FIG. 9 shows a representation of search tools associated with mediaservices. Considering the scenario above, one or more of computingdevices 102, 110, and 112 may receive the indication of the searchand/or browse tool in representation 710 and 810 to initiate therepresentation 910. As shown in FIG. 9 and further described below, therepresentations 910-960 may also be a part of the music discoveryprocess. For example, representation 910 may be displayed on a computingdevice in media playback systems 106 and/or 108 to facilitate the musicdiscovery process. As shown, representation 910 illustrates a searchtool, possibly an alpha-numeric search tool.

In some examples, each search tool of the plurality of search tools maybe associated with at least one respective media service. As shown inFIG. 7, a user may select the “It's a Thursday afternoon . . . ” searchtool in the representation 710 that may be associated with the service740, possibly a service by music curators for providing media such asSongza™.

As such, the user may have the option to“subscribe” to the service 740 selecting the “+” indicator but may notbe required to subscribe to the service to use the “It's a Thursdayafternoon . . . ” search tool.

As shown in FIG. 8, a user may select “The Sentence” search tool in therepresentation 810 that may be associated with the service 840, possiblya media service supporting full-sound headphones such as Beats Music™.As shown in representation 820, the service 840 may facilitate the musicdiscovery process by providing “The Sentence” search tool. As such theuser may have the option to “subscribe” to the service 840 selecting the“+” indicator but may not be required to subscribe to the service to use“The Sentence” search tool.

As shown in FIG. 9, the alpha-numeric search tool in the representation910 may be associated with various services. In particular, by entering“Air” in the search input as the name of an example musical artist,various categories may be provided in the representation 920. Althoughthese categories may be associated with various services, they may begrouped and provided based on functionality of the various services. Forexample, the Air radio category may be provided based on radio servicesand/or online radio stations or services. The top tracks category may beprovided based services that provide top tracks, possibly including toptracks rated by critics and other listeners. The albums category may beprovided based on services that provide album details such as albumcovers, artist background information, the number of tracks in thealbum, and track lengths, among other possibilities. The similar artistscategory and the influential artists category may be provided basedservices that maintain similar types of music or influential genres ofmusic, for example.

Yet further, the categories may also be associated with services. Airradio category may be associated with radio services 1-3 in therepresentation 930. The top tracks category may be associated withmultiple music library services for purchasing tracks 1-3 in therepresentation 940. The albums category may be associated withalbum-downloading services for downloading albums illustrated in therepresentations 950 and 960. The similar artists category and theinfluential artists category may also be associated with music libraryservices. Further, a music curation category may be associated withmusic curation services that collect, sort, and/or stream content thatmay obtained from various media sources. For example, such musiccuration services may include services developed by music experts thathave pre-programmed stations covering various music genres, artists, andtrends in music culture.

In addition, each search tool in FIGS. 7-9 may result in searches beingperformed by media services that support the respective search tool. Forexample, the “Search” tool illustrated in the representations 710 and810 may be supported by various types of media services such as, forexample, media services described above in relation to representations930-960. Yet, the “It's a Thursday afternoon . . . ” search tool may besupported by service 740, possibly a service by music curators forproviding media such as Songza™. Further, “The Sentence” search tool maybe supported by service 840, possibly a media service supportingfull-sound headphones such as Beats Music™.

Referring back to FIG. 5, it should be noted that the representations inFIGS. 7-9 may be displayed as part of the controller interface 500. Forexample, one or more of the representations from FIGS. 7-9 may bedisplayed in the playback status region 530, the playback queue region540, and/or the audio content sources region 550, among other possibleregions in the controller interface 500. As such, part of the musicdiscovery process may be integrated in the controller interface 500.

b. Receive Indication of Media Characteristic

Returning back to FIG. 6, at block 604, the method 600 involvesreceiving by the computing device an indication of a mediacharacteristic, where the computing device receives the mediacharacteristic via the indicated search tool. For example, one or moreof computing devices 102, 110, and 112 may receive the indication of themedia characteristic using an indicated search tool. In particular, acomputing device in the media playback systems 106 and/or 108 mayreceive the indication of the media characteristic and send theindication to one or more of the computing device 102, 110, and 112. Assuch, the computing devices 102, 110, and 112 may receive the indicationof the media characteristic over the cloud network 114.

As shown in FIG. 7, an indication of a media characteristic may bereceived using the “It's a Thursday afternoon . . . ” search tool in therepresentation 720. For example, the indication of the mediacharacteristic may include a selection of “Brand New Music”, “Music toBoost Your Energy”, “Music for Working (No Lyrics)”, “Calm & MellowMusic”, and “Office Music”, among other possible selections. Asillustrated by the ellipses, there may be other selections in therepresentation 720 to indicate the media characteristic.

As shown in FIG. 8, an indication of a media characteristic may bereceived using “The Sentence” search tool in the representation 820. Forexample, after the words, “I′M”, an input, “AT HOME”, may be entered toindicate a location associated with the media characteristic. Further,after the words, “& FEEL LIKE”, an input, “DANCING”, may be entered toindicate a desired action associated with the media characteristic. Yetfurther, after the words, “WITH”, an input, “FRIENDS”, may be entered toindicate desired people that may be associated with the mediacharacteristic. In addition, after the words, “TO”, a mediacharacteristic, “ELECTRONIC DANCE MUSIC”, may be entered to indicate agenre of music associated with the media characteristic. As such, theplay button 822 may be selected to “play the sentence” and “TheSentence” search tool may be able to facilitate the music discoveryprocess based on the indicated media characteristics.

As shown in FIG. 9, an indication of a media characteristic may bereceived using the alpha-numeric search tool in the representation 910.For example, the word, “AIR”, may be entered into the search input ofthe alpha-numeric search tool. In general, media characteristics mayinclude data, metadata, and/or information related to media or mediaitems. Examples of media characteristics may include alpha-numericcharacters of an artist name, a band-member's name, a name of a song, atitle of an album, and/or a record label's name that produced media,among other possibilities.

In addition, the representation 910 may include a browse tool forbrowsing various artists that may have a name similar to “Air” such as“Airborne” and “Air Supply”, for example. As such, media characteristicsmay include alpha-numeric characters input in the search tool and/orvarious indications or selections while browsing in the browse tool inthe representation 910. As illustrated by the ellipses, there may beother artists in the representation 910 to browse in the music discoveryprocess.

c. Selecting Media Service that Maintains Media Associated withIndicated Media Characteristic

At block 606, the method 600 involves selecting by the computing deviceone or more of the at least one respective media service that maintainsmedia associated with the indicated media characteristic. For example,one or more of computing devices 102, 110, and 112 may select one ormore services of at least one respective service that maintains mediaassociated with the indicated media characteristic. As described below,these computing devices may select one or more services maintainingmedia, for example, media including certain sounds, genres of music,musical artists, albums, songs, tracks, musical notes, and digital audiofiles, among other types of media.

In some examples, one or more services that maintain media associatedwith the indicated characteristic may be selected based on an indicationof a search tool. For example, the one or more services may be selectedfrom receiving the indication of a search tool from among a plurality ofsearch tools as described above in block 602 of the method 600. As shownin FIG. 7, by selecting the “It's a Thursday afternoon” search tool inthe representation 710, a computing device may select the service 740for that maintains media. For example, the media may be associated withthe indicated media characteristic as described above.

As shown in FIG. 8, by selecting “The Sentence” search tool in therepresentation 810, a computing device may select the service 840 thatmaintains media. For example, the media may be associated with theindicated media characteristics as described above. In particular, themedia may be associated with the media characteristics indicating alocation, a desired action, desired people, and/or a genre of music,among other possible indications.

As shown in FIG. 9, by entering the media characteristic inrepresentation 910, a computing device may determine categories ofservices that maintain media. For example, the computing device maydetermine or identify the air radio category, the top tracks category,the albums category (which may also be an album-downloading category),the similar artists category, and the influential artists category,among other possible categories indicated by the ellipses in therepresentation 920.

As further shown in FIG. 9, the computing device may select one or moremedia services that maintain media associated with the indicated mediacharacteristic. For example, the computing device may select radioservice 1 (e.g., Pandora® Radio), radio service 2 (e.g., Slacker®Radio), and radio service 3 (e.g., iTunes Radio℠), among other possibleradio services indicated by the ellipses in the representation 930. Asshown in the representation 930, the option to “subscribe” to radioservice 1 may be provided. As such, a user may subscribe to radioservice 1 by selecting the “+” indicator but may not be required tosubscribe to radio service 1 to listen to radio service 1.

In another example, the computing device may select or identify track 1,track 2, and track 3 of the top tracks category, among other possibletracks indicated by the ellipses in the representation 940. Further, asshown in the representation 940, the option to buy tracks such as track1 may be provided. In particular, a user may buy track 1 by selectingthe “buy” indicator which may provide music library services such asGoogle Play™, Amazon.com®, and/or a local purchasing service, amongother possible services for purchasing track 1. In some instances, onemusic library service (e.g., Google Play™) may be provided to purchasetrack 1, another music library service (e.g., Amazon.com®) may beprovided to purchase track 2, and yet another music library service(e.g., Rhapsody® Music Service) may be provided to purchase track 3.Further, the user may not be subscribed to or registered with any ofthese services to view such services for purchasing tracks 1-3. Inaddition, the name of the service may or may not be displayed, possiblyunless a registration is required to obtain the track.

In yet another example, the computing device may select or identifyalbum 1, album 2, album 3, and album 4 of the albums category, amongother possible albums indicated by the ellipses in the representation950. Further, as shown in the representation 950, the option to buyalbums such as album 2 may be provided by album-downloading services. Inparticular, by selecting album 2, the representation 960 may be shown toallow a user may to buy album 2. For example, a user may buy track 1 byselecting the “buy” indicator which may provide music library servicessuch as Google Play™, Spotify®, and/or a local purchasing services,among other possible services.

Further, requests for the media may not be sent to the media services inFIG. 9 until a particular media service is selected in representations930, 940, 950, and 960. For example, requests to the radio services 1-3may not be sent until one or more of radio services 1-3 inrepresentation 930 are selected.
